Cost Allocation Example
Dialglow Corporation manufactures travel clocks and watches.
Overhead costs are currently allocated using direct labor hours, but the controller has recommended an activity-based costing system using the following data:

Production Setup
Cost Cost Driver
$120,000 No. of setups
Material Handling
& Requisition
30,000 No. of parts

Using Traditional Costing System
Allocate Total OH based on labor hours
(35,000 hours for travel clocks; 105,000 hours for watches.)
OH Rate:
$210,000 / 140,000 hours = $1.50/hour
OH cost per Travel Clock:
($1.50/hr * 35,000 hrs) / 45,000 units = $1.167
OH cost per Watch:
($1.50/hr * 105,000 hrs) / 75,000 units = $2.10

Using ABC
Allocation of :
Production Setup Costs: $120,000 / (10+15) setups = $4,800/setup
Material Handl’g Costs: $30,000 / (18+36) part numbers = $555.56/part
Packing/shipping Costs: $60,000 / (45,000+75,000) units = $0.50/unit shipped
